PLS-01455: The predicates IS NULL and IS NOT NULL are
defined only for column specifications
Answer / guest
Cause: The predicates "IS NULL" and "IS NOT NULL" are
defined only for column specifications, not for any other
expressions. Section 5.15, "<null predicate>", indicates
that in the predicate "x IS NULL", x must be a column, and
may not be any other kind of expression.
Action: none
